TPG and Dragoneer get to convert the debt to equity at a 20% discount of whatever share price Spotify sets for an eventual IPO. And if it doesn’t IPO within the next year, that discount goes up 2.5% every extra six months. Spotify also has to pay 5% annual interest on the debt, and 1% more every six months up to a total of 10%. And finally, TPG and Dragoneer can sell their shares just 90 days after the IPO, before the 180-day lockup period ends for Spotify’s employees and other investors.
